DANIEL SNELL, OF HARMONY, INDIANA.

WINDOWMFASTENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 709,726, dated September 23 1902.

Application filed May 14, 1902. Serial No. 107,321. (No model.\

Be it known that I, DANIEL SNELL, a citizen of the United States, residing at Harmony, in the county of Clay and State of Indiana, have invented new and useful Improvements in Window-Fastening Devices, oi which the tollowing is a specication.

My invention relates to improvements in .window-tastening devices; and the object of the same is to construct'. a device of this character which will be sim ple in construction an d eflicient in operation.

The novel construction employed by mein carrying out my invention is fully described in this specilication and claimed, and illustrated in the accompauyiugdrawings, forming a part thereof, in which- Figure l is an elevation of a window partly in section and equipped with my device. Fig. 2 is a detail of my device. Fig. 3 is a detail of the same with cover removed. detail of one ot' the bolts.

Like numerals of reference designate like parts in the different views of the drawings.

The numeral 1 designates a window-frame having a sash 2 slidiugly mounted therein. A rack 3 is attached tothe frame adjacent to the sash and has a series of rectangular apertures I therein, which are slightly beveled at 5 on the upper and lower sides. Mounted on the sash 2, adjacent to the rack 3, is a casing 6, having perforated ears 7 thereon, which are apertured to accommodate screws 8. The casing o is rectangular, is subdivided by a horizontal partition 9, and is provided with a snugly-fittiug cover IO. Two bolts ll and l2 areslidingly mou nled in the casing in position toengagethe rack 3. Theouterendofthebolt and 12 are each provided with lugs I3,\vl1ich engage shoulders 13b, formed on the casing, and limit the outward movement of the bolts. Slots 13a are formed in the ends of the bolts 11 and 12, and crosspins l5 extend trans- Fig. 4 is a' versely these slots I4 and are engaged by the lower forked arms 16 of elbow-levers 17, which arms extend through apertures lo, formed in the cover IO of the casing. The levers 17 are l'ulcrumed on a rod 1S, supported by two lugs 19. The upper long arms 2O ot' the levers 17 are provided with thumb-pieces 20, and a spring 2l, surrounding the rod I9 and engaging the levers I7, holds the bolts Il and l2 in engagement with the rack 3.

In the operation of raising the wiudow-sash the upper bolt 1I is retracted by operating the corresponding lever 17, when the window can be raised and the bolt l2 will ride over the rack 3 on the upward movement, but will prevent all downward movement. In lowering the window the bolt l2 is retracted by means of the lower lever 17, when the bolt Il will engage the rack and serve as a brake.

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a window-fastening, the combination of a rack having rectangular apertures thereon rounded off on their upper and lower edges, a casing mounted on a sliding sash, a bolt slidingly mounted in said casing and having a beveled head constructed to positively engage the said rack to hold the window against being raised, a bolt slidingly mounted in said casing and having a beveled head constructed to positively engage said rack to hold said window against being lowered, said bolts having slots in their ends, pins mounted transversely said slots, a rod mounted ou said casing, elbow-levers fulcrumed on said rod and bearing thumb pieces, said levers having forked arms which engage said pins, and a spiral spring mounted on said rod and arranged to actuate said levers, substantially as described.

In testimonywhereof I have hereunto Set my hand in presence oi two subscribing wituesses.

DANIEL SNELL.
